Israel Adesanya and Alexander Volkanovski put their respective middleweight and featherweight titles on the line at UFC 276.
Adesanya, ranked No.3 in the men's pound-for-pound rankings, has dominated the middleweight division since stepping into the UFC octagon in 2018, winning all 11 of his fights.
The Nigerian's only career loss came when he stepped up to fight light heavyweight champion Jan Blachowicz in 2021.
He makes the fifth defence of his middleweight strap in Las Vegas and can be backed at 2/9 to defeat 13/5 Jared Cannonier, who is ranked No.2 in the division.
Cannonier had previously struggled to find his place in the light heavyweight division but looks much more comfortable at middleweight.
Tha Killa Gorilla has won five of his six bouts at 185lbs but his only defeat came against Robert Whittaker, who has lost twice to Adesanya.
The co-main event at UFC 276 also has a title on the line when 8/15 Volkanovski takes on 6/4 Holloway for a third time.
Volkanovski has won the two previous meetings, taking the featherweight title from Holloway at UFC 245 before successfully defending in a rematch at UFC 251.
The Australian is unbeaten in 21 fights with 11 of those coming in the UFC and he's No.2 in the men's pound-for-pound rankings.
Holloway has secured back-to-back wins after those two defeats to Volkanovski and will be seeking revenge at the T-Mobile Arena.

How to watch
Israel Adesanya 2/9, Jared Cannonier 13/5, Alexander Volkanovski 8/15, Max Holloway 6/4
Adesanya is undoubtedly one of the best to ever compete in the middleweight division but he has a chance to further cement his legacy at UFC 276.
He's currently tied for the most consecutive wins in the UFC's middleweight division (11) with Anderson Silva and looks set to surpass the Spider on Sunday.
If he comes through successfully against Cannonier, there aren't many hugely appealing fights left in the division, having beaten the majority of the current top-six, so a move up to light heavyweight could potentially be on the cards.
There's plenty of intrigue in the co-main with Holloway seeking redemption against Volkanovski.
It's clear that Volkanovski and Holloway are levels above the rest of the featherweight division but, so far, the latter has struggled to match his rival after suffering two defeats.
Both of those losses, however, came via decision and another 25-minute classic could be on the cards in Las Vegas.
Like Adesanya, Volkanovski, who is unbeaten in 21 fights, has hinted at switching weight class if he prevails again.
Sunday's event is hosted at the T-Mobile Arena in Nevada, United States.
